Organ System/Disease Focus
Cardiovascular Disease, with a focus on the genetic and molecular basis of genetic dilated cardiomyopathys



I am a cardiovascular clinician-scientist and a cardiac patient, having undergone a combined heart and kidney transplant in 2020 for a familial (genetic) dilated cardiomyopathy resulting from a mutation in the LMNA gene. My current research focuses primarily on pre-clinical studies of novel therapeutics for LMNA-associated familial dilated cardiomyopathy, employing the murine double knock-in model of my own mutation (lmnaN195K/N195), which faithfully recapitulates the human disease as well as induced pluripotent stem cell-derived cardiomyocytes carrying the N195K mutation (differentiated from my own induced pluripotent stem cells). We are currently exploring the role of impaired autophagy in the pathogenesis of cardiac dysfunction accompanying these mutations, and developing novel autophagy agonists as potential therapies for this aggressive form of heart failure that responds poorly to conventional therapy.
